STOVEPIPE.

SPECIFICATION forming part of Letters Patent No. 539,334, dated May 14,1895.

i Application filed June 16, 1894. Serial No. 514,749. (,No model.)

To all whom it may concern:

Be it known that I, GEORGE BROWN BAR- CLAY, molder, a subject of theQueen of Great Britain, residing at Joliet, in the county of Will andState of Illinois, have invented a new and useful Improvement inStovepipes, of which the following is a specification.

The object of my invention is to make a stove pipe the circumference'ofwhich .can easily be increased or diminished by means of a sliding jointor seam, thereby facilitating the fitting of the same.

The invention consists of the combination of two sheet iron socketssecured to the sheet iron of the pipe, one socket being on each side oftheseain and a V shaped piece of wire or metal that Works in the socketsin such a manner as to close the seam and to increase or diminish thecircumference of the pipe as the V shaped wire or fastening is moved upor down in the sockets.

The manner in which I attain my object is more fully illustrated by theaccompanying drawings, in which- Figure l represents a perspective viewof a single joint of pipe completed. Fig. 2 represents a perspectiveView of the two sockets and the V-shaped fastening or Wire placed inthem. Fig. 3 represents a perspective view of the double fold and clearedge. Fig. 4 represents the V- shaped fastening or wire seen from directfront view. Fig. 5 represents the V-shaped fastening or Wire as viewedat an angle of aboutforty-five degrees to one side from the view in Fig.4l.

a represents the pipe com pleted of the usual material.

b b represent the two sheet iron sockets at one extremity of the pipe,one on each side of the seam.

c represents the V shaped fastening or wire which is placed in and is towork up and down in the sheet iron sockets.

d represents a rivet which secures the seam at the opposite extremity ofthe pipe when fastening is used at one end only. The rivet is made so asto allow alittle play of the seam around it as a pivot when the V shapedfastening or wire is moved up lor down in the sockets.

c represents the double fold which is formed so as to receive the clearedge f into the second fold. The clear edge fat the extremity which issecured by the rivet has its corner rounded off so as to allow a slightmotion on the rivet when the fastening'is operated.

I prefer that the fastening piece, c, should be made of Wire of a sizesufficient to give the requisite stiness, and that it should be shapedas shown in the drawings, that is to say, with the diverging legs, c',c', which fit into the sockets, b. The cross connecting piece ybetweenythe legs is provided with an outward projecting'folded portion, c2,which serves as a handle by means of which the fastening may be slid inthe sockets, b.

By the use of a coupling or fastening piece such as I have-shown, Iproduce a device which may be easily operated, and which acts positivelyto change the size of the pipe whichever way it be moved. Thus, When thefastening is moved down the opposite edges of the pipe are positivelydrawn together, and when the fastening device is moved upward or in theopposite direction, the edges of the pipe are positively separated andthe size of the pipe increased.

I make no claim to the V shaped fastening or wire c, or the sockets b b,or the double fold c, or the clear edgefwithin or of themselves. j

I claiml. A pipe section provided with one folded or doubled edge withwhich the opposite edge is adapted to engage to` form a close seam orjoint, in combination with the sockets, b, b, secured to the pipesection near its opposite edges, and the fastening piece, c, havingdiverging legs which have bearing in the said sockets, substantially asset forth.

2. In combination with a pipe section the edges of which are adapted tobe brought together to form a close or tight joint or seam, the sockets,b, h secured to the pipe section near its opposite edges, and thefastening piece, c, having the diverging legs, c', c', adapted to engagewith the said sockets, and the cross connecting piece between the legsprovided with an outward extended folding portion, c2, which serves as ahandle for manipulating the fastening, substantially as set forth.
